## When to prefer this

Choose this endpoint when you specifically need vault share price history over time (as opposed to APY, TVL, or reward breakdowns). It is the right choice for charting price appreciation, backtesting yield strategies, or analyzing how a vault's net asset value per share has evolved. Use sibling endpoints for APY/TVL breakdowns or reward data.

## Known failure modes

- Invalid or unsupported network identifier returns a 404 or error response
- Unknown or incorrect vault ID returns no data or an error
- Time range parameters outside available data history may return partial or empty results
- Network connectivity issues may cause timeouts
- Rate limiting may occur with high-frequency requests

## How this service works

Retrieves time-series historical TVL data for a specific vault, including base yield and rewards components over a customizable time range

## Output

A time-series dataset of historical share prices for the specified vault, with data points indexed by timestamp showing how the vault's share price has changed over the requested time range. Each entry typically includes the timestamp and share price value, enabling charting, backtesting, and performance analysis.
